Seaborn Stock Bending Dies
We have stock dies as follows with Center Line Radius as shown. These die sets may all be used on Aluminum, Steel or Stainless Steel. If you do not see a mandrel listed for a wall thickness you want these are only $150 -200 typically and ot required for many jobs in particular with heavier walled Tube.
We have stock dies set for ¾” to 2” Pipe. Our machines are capable of bending up to and including 3” diameter tube. The min radius we can bend is approximately 50mm with our current tooling posts. New dies sets for a single radius typically cost between $3,000 and $5,000.

Why Choose Seaborn Manufacturing for Tube Bending
Tube Bending for Different Materials
Steel Tube Bending
Carbon steel alloys are the most commonly used material in tube bending and metal fabricating in general. From common every day tube such as ASTM A1011, 44W , 50W, to high strength tubes such as 4130,4140, often called chromoly.
Tube is formed to be used in everything from the chair we sit on to the roll over protection systems that keep us safe in motor sports. The majority of tube bending is from one or another steel alloy.
Stainless Steel Tube Bending
Unknown to many is that stainless tends to very good for tube bending. Usually chosen either for its raw appearance or chemical resistance. Stainless tube forms are and effective solution for many.
Aluminium Tube Bending
The biggest single issue in aluminum tubebending is acquiring suitable material for the task. This can be quite a hit or miss process and often ends involving some pretty high shipping costs. The bulk of aluminum tube is 6061-T6 and absolutely useless for tube bending. The most common bendable grade of aluminum tube is 6063-T5 and not nearly as available. We have gone so far as buying entire extrusion runs to acquire what we needed.
Wall Thickness and Tube Bending
Contrary to the common perception it is easier to produce clean bends in a thicker walled tube (with in reason) than a thinner wall tube. Our machines have the power to bend the tube and thicker tube walls help maintain the shape of the tube. We would rather bend 1”diameter 0.125” wall tube than 1” 0.065 wall tube any day.
Square Tube Bending
Square tube offers certain challenges. The I.D. and O.D. wall of the tube really wish to collapse to the center. When you try to bend a square tube tight and do not allow for some collapse the tube can literally be torn while bending from it crimping onto the mandrel.

Tube Bending Services FAQ
We provide CNC tube bending for various materials including steel, aluminum and stainless steel.
No we can not. The most common tube grade 6061-T6 can not be bent. We have had success with 6061-T1. Most commonly we bend 6063-T5 for aluminum tube bending.
Our current size range is from 3/4″ to 2.375″ in diameter, and similar in square. Feel free to request our list of stock tooling.
Absolutely. We provide accurate tube bending with and without full mandrel, depending on part requirements and material specifications.
Tube bending is the forming of tube around a central die while encapuslating the tube so it maintains its profile.
Tube bending most commonly is for mild steel. Stainless is well suited to tube bending and some grades of aluminum bend well. Copper, Inconel alloys, and many exotics are and can be used in tube bending.
Same as every job. Tooling cost need to be addressed first if stock tooling can not be used. After that is set up time to instal tooling and prove the first formed parts. Scrap cost of parts expected to be lost in set up. Then finally the run cost per part. The cost per part does not change throughout a run but how many pieces the initial costs are amortized over has a big effect on piece price.
